CHURN.

SPECIFICATION forming part of Letters Patent No. 439,697, dated November 4, 1890.

Application iiled May 4,1889. Serial No. 309,602. (No model.)

T0 LZZ whom t may concern:

Be it known that I, JAMES P. SINOLAIR, of Mottville, Onondaga county, New York, have invented certain new and useful Improvements in Churns, of which the following is a description, reference being had to the accompanying drawings, forming part of this specication.

My invention consists in certain new features of construction by which the power used to swing the churn is applied and used more economically than is usual in this class of machines.

It also consists in certain new features of construction by which the milk within the churn is caused to wash the upper portion of the churn more perfectly than heretofore.

Figure l is a sectional side view of my improved churn. Fig. 2 is a partial section of the same. Fig. 3 is a detail view in perspective, showing` the coverfastening devices. Figa is apartial end view of the same. Fig. 5 is an enlarged detail showing spring and bolt connections.

My invention is constructed as follows: A body portion A is provided with curved ends, as shown, and the sides of this body being extended beneath the churn-bottom form rockers a a,Fig. 2. A supporting-frame D is provided with a pair of parallel ways B B, arranged so that the churn-body may rock thereon upon its rockers a a.

Motion is imparted to the churn by means of a belt b, attached at its ends to the churnbody and thence passing around the pulleys m fm. A pitInan p is attached to this belt IJ and is reciprocated by means of a crank E. However, I wish it to be clearly understood that this actuating mechanism is not essential to my invention, and accordingly I show at c e a hand-rail at either end of the churnbody, by which it may be rocked, in which case the beltb should be slipped off from the pulleys m, m or else detached from the end of the pitman p.

A spring S is bolted or otherwise secured under the ways B upon each side of the churnframe and its free end is secured to a bolt c, which passes through B and is provided with a head c. A curved spring r is pierced at its center to pass the bolt c through it, and being secured to the bottom of the rocker a holds the head of the bolt c toits place at the center of the rocker. The spring r lays between the rocker ct and the way B, and as the churn-body is rocked away from its central position both the springs r and s tend by their resiliency to draw it back to the medial position, while the bolt c prevents the rocker a from sliding upon the way B. Each side of the churn is thus provided with the aforesaid springs r and s, and by this means the inertia of the swaying contents of the churn-body stores up power in these springs to swing the churn and its contents upon the return Inovement.

The opening by which the churn is charged I provide with a pair of folding doors or gates g g, which are secured by hinges h h, the upper leaves of which are slotted for the reception of clamping-bolts in a cross-bar K, which rests in brackets Z Z upon the sides of the churn-body. By this construction these gates g g may be depressed a greater orless amount, so that although the churn-body may be more or less full of cream it will always wash their lower surfaces at each swing.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

l. In a churn, the combination, with the body A,provided with rockers a, of the ways B, for supporting said rockers, the springs S S, attached to the under sides of the said ways, and the bolts c, passing through the said ways and connecting the said rockers with the said springs, whereby the churnbody will be reacted and the rockers retained upon the said ways, substantially/as set forth.

2. In a churn, the combination', with the body A, having the rockers a d, of the ways A B B, the springs r r, interposed between the said rockers and ways, the springs S S, attached to the under side of the said ways, and the bolts c c, passinoF through the said ways and connecting the said rockers with the said springs.

3. In a churn, the combination, with the rocking body A, provided with the curved ends, as shown, and with the cross-bar K, of gates g g, the hinges h 7L, the upper leaves of which are slotted, and a clamping-bolt passing through the said bar and slotted leaves, whereby the said gates may be secured in different positions to change their inward inclinations, substantially as set forth.
